Application filed June 18, 1913. Serial No. 774,447.

To all whom it may concern:

Be it known that I, GEORGE E. SLATER, a citizen of the United States,residing at Graceville, in the county of Jackson and State of Florida,have invented a new and useful Churn- Operating Mechanism, of which thefollowing is a specification.

The present invention appertains generally to churns, and relates moreparticularly to a novel and improved mechanism for actuating churns.

One of the objects of the present invention is to provide a mechanism ofthe character indicated applicable to various churns, for operating thesame, in a convenient and efficient manner.

Another object of the present invention is to provide a mechanism ofthat character embodying an adjustable base or platform for the churnbody, in order that the mechanism may accommodate various sizes, orproportions of churn bodies.

A further object of the present invention is to provide novel means foradjusting the stroke given the dasher staff or rod, in order that thedasher may be actuated through a predetermined distance, according tothe size of the churn body.

A still further object of the present invention is to rovide a mechanismof the character specified embodying a novel and improved frame forreceiving and holding the churn body, the actuating mechanism beingattachable with the ordinary dasher staff for reciprocating the same.

With the foregoing and other objects in view, which will be apparent asthe description proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being under stood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

The invention has been illustrated in its preferred embodiment in theaccompanying drawings, wherein Figure 1 is a perspective view of themechanism, as in use. Fig. 2 is a fragmental elevation of the device,illustrating the gear or means for actuating the dasher staff. Fig. 3 isanother elevation of the parts depicted in Fig. 2, this view being takenat right angles to the line of view of Fig. 2, and parts being shown insection.

In carrying out the present invention, reference being had in detail tothe drawings, there is provided a suitable supporting frame denotedgenerally by the numeral 1. This frame is preferably constructed ofstrips or bars, and embodies a pair of parallel bars 2 having their endsbent downwardly into feet 3 for supporting the frame on the floor orother surface. The frame further includes a pair of inverted V-shapedbars 4 carried by the bars or base members 2. Each of the bars orstandards 4: has its ends or limbs riveted upon the respective bar orbase member 2 adjoining the respective feet 3, it being observed thatthe standards or upright members 4 are disposed parallel with eachother. The apices of the stand ards or supports 4 are connected by across piece or beam 5, and one pair of limbs of the standards 4 arepreferably connected by diagonal braces 6 to steady the frame orstructure.

The frame 1 is provided with novel means for supporting the churn body,and to this end, four vertical or upright strips 7 have their respectiveends riveted to the bars 2 and the respective limbs of the standards 4.The strips or upright members 7 are each provided with a series ofkey-hole openings 8, the heads of which are disposed uppermost, and thetails of which extend downwardly. The platform or base'9 is adapted tobe supported by the strips 7 the said platform having the headed studs10 at its corners, and the studs being adapted to engage through therespective key-hole openings 8 to support the platform, it beingobserved that the platform may be adjusted vertically by engaging thestuds through the key-hole openings at various heights. In engaging theheaded studs 10 in the respective keyho e openings, said studs are firstengaged through the heads of the key-hole openings, and the platform insettling or gravitating will cause the studs to move into the tails ofkey-hole openings to tightly and firmly hold the platform in position.It is evident that the strips 7 are adapted to be sprung in engaging anddisengaging the platform or base to and from the said strips.

Upon the platform or base 9 is seated or disposed any ordinary churnbody 11, into which the usual dasher staff or red 12 extends. It will beunderstood that the present staff is adapted to pass through anaperture.

13 provided inthe central portion of the beam 5, so that the free orouter end of the dasher staff protrudes above the beam 5, or the frameof the device.

As a means for actuating or reciprocating the dasher staff, there hasbeen provided the following structure: A suitable frame denotedgenerally by the numeral 14, is carried by the main frame 1 of thedevice, the supplemental or gear frame 14 being more or less arbitrarilyor conventionally illustratedin' the drawings. As illustrated, the frame14 embodies a cross strip or bar 15 terminallyv riveted or secured tothe respective limbs of the standard 4, and a similar cross strip or bar16 is similarly secured to the said limbs intermediate the apices andthe lower ends of the standards, the strip 15 being disposed adjoiningthe apices of the standards. The frame 14 further includes an angularbar 17 terminally secured to the respective strips or bars 15 and 16, sothat its arms are disposed vertically and horizontally, respectively.Similar angular bars 18 have their ends or terminals riveted or securedto the respective limbs of the standards, adjoining the respectivestrips 15 and 16, the arms of the bars or members 18 being disposedhorizontally and vertically, respectively. The elbows of the respectivebars or angular members 18 and 17 are disposed in opposite directions,as clearly seen in Fig. 3. A cross strip or bar .19 is terminallysecured to the elbows of the angular members 18, while an upright strip20 is terminally secured to the strips 19 and 16 intermediate theangular members 18. An upright member or standard 21 is carried by thelower horizontal arm of the angular member 17. The frame 14 carries asuitable train of gears adapted to be actuated by hand, forreciprocating the dasher stafi, as will hereinafter appear. An actuatingshaft 22 is journaled through the upright arm of the member 17 andthrough the upright strip 20 adjoining their upper ends, and has asuitable hand crank 23 at its outer end. A large gear wheel 24 is keyedupon the shaft 22 adjoining the member 17 and a counter shaft 25 isjournaled through the members 17 and 20 below the shaft 22. The countershaft 25 has a pinion 26 keyed thereon which intermeshes with the gearwheel 24, the pinion being of relative small diameter, in order that theshaft 25 will be rotated at a greater velocity than the shaft 22. Theshaft 25 also carries a balance or fly wheel 27 in order to assist thetrain of gears in running easily. A second counter shaft or crank shaft28 is journaled through the member 17 and through the pedestal 21 belowthe shaft 25, and has a gear wheel 29 keyed thereon intermediate themember 17 and pedestal 21. The gear wheel 29 intermeshes with the pinion26. The inner end of the crank shaft 28 projects beyond the member 17, abalance or fly wheel 30 being mounted on the shaft 28 adjoining itsinner end. The balance wheels 27 and 30 permit the actuating gears torun easily or lightly, it being noted that the entire actuatingmechanism is compact. The crank shaft 28 is operativelyconnected withthe dasher staff in a novel manner and to this end, an extensibleor'adjustable crank 31 is secured to the inner end of the shaft 28. Thecrank embodies a slotted section 32 secured to the shaft 28 and a secondsection 33 carrying set screws 34 working through the slot of thesection 32, in order that when the set screws are tightened, thesections 32 and 33 will be locked in position with respect to eachother. The set screws permit of the adjustment of the crank, as will beapparent. The outer section 33 carries the wrist pin 35, said wrist pinbeing adjustable with the section 33 in order that it maybe disposed atvarious radii with respect to the aXis of the shaft 28. The pit-man 36is loosely connected to the wrist pin 35 and is attachable at its upperend with the upper end of the dasher staff. The pitman 36 isconveniently coupling 37, which embodies a clamp 38 to embrace the upperportion of the dasher staff 12 and to which the pitman 36 is pivoted.The pitman is conveniently pivoted to the clasp 28 by means of a secondclamp 39 embracing the pitman and pivoted to the clamp 38. s

In use, it is evident that the present device may be readilyadjusted toaccommodate various hand churns. Thus, the platform 9 may be adjusted tothe proper height to accommodate the particular churn body, while thecrank 31 may be adjusted to give a proper throw or reciprocation to thedasher staff 12, it being observed that the pitman 36 is readilyattached to the dasher staff. By rotating the crank 23 manually, thedasher staff may be reciprocated through the meiio dium of the gears,crank and pitman, it

iso

capabilities of the present invention will be apparent to those versedin the art, it being observed that the objects aimed at have beencarried out satisfactorily, and that the present device is a desirableone for the purposes for which it is designed.
